WINDOW-OPERATING DEVICE.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Original application filed 0ctober14,1918, Serial No. 257,952. Dividedand this application filed December 1 0 all whom it may concern:

Be it known that I, CLARENGE VIc'ror. Jones, a citizen of the UnitedStates of America, and resident of 230 Yonge street, city of Toronto,county of York, Province of Ontario, in the Dominion of Canada, haveinvented certain new and useful Improvements in lVindow-OperatingDevices, of which the following is a specification.

The invention relates to improvements in window operating devices asdescribed in the present specification and illustrated in theaccompanying drawings that form a. part of the same.

The invention consists essentially of the novel means employed forsecuring a window in any desired position against the pressure ofsprings adapted to open same.

The objects of the invention are to provide a means whereby casementwindows opening to the outside may be adjusted without the necessity ofthe operator reach ing out of the window, to avoid displacement ofscreens and the like when adjusting the window, to prevent damage causedby windows being blown open and shut and generally to provide a windowoperating device which will be inexpensive to manufacture, durable andefficient.

This application constitutes a division of my application, Serial No.257,952 filed October 14th, 1918.

In the drawings Figure 1 is a view of a window locked to an openposition.

Fig. 2 is a cross sectional view taken on the line AA of Fig. 1.

Fig. 3 is a detail of a portion of the chain secured in the lockingbracket.

Fig. 4 is a detail of two of the links of the chain.

Fig. 5 shows a modified form of link.

Like numerals of reference indicate corresponding parts in the variousfigures.

Referring to the drawings the window 1 is provided with two or morereverse hinges 2 adapted to exert an outward pressure on said window toopen same, (the construction of said hinges being described and claimedin my previous application.)

The outward movement of the window caused by the pressure of the springhinges 2 is controlled by means of a chain 3 secured at one end of thewindow sash in any suitable form of swivel attachment 4, (it thought notto be necessary to show said Serial No. 266,119.

swivel attachment in the drawings as any of the known forms may be used)and having its other end operating through a catch or bracket 5.

The chain 3 is composed of solid metal links 6 perfectly circular incross section, one end of each of said links being provided with acentrally disposed flat projection 7 having its end tapered inwardly asat 8 and the other end of each of said links having a centrally disposedlongitudinal slot 9 therein adapted to accommodate the projection 7 fromthe adjacent link and to be secured thereto by a pin 10. The inner endwall of the slot 9 is cut at an angle corresponding and the end of theprojection 7 so that links will fold in one direction only.

The bracket or look 5 through which the chain 3 operates is preferablyformed from a flat piece of metal having its side edges turned inwardlyat right-angles forming vertical flanges 11 and 12, the flange 11 beingcut away toward its lower end and being provided with a circular openingadjacent to the upper end thereof adapted to accommodate said chainwhile the upper end of the flange 12 terminates slightly below theopening in the flange 11 to permit of the chain projecting in a straightline from said openlng.

In Fig. 5 a modified form of chain is shown in which the links areformed in two longitudinal sections secured together and spaced at oneend by a fiat member 13 corresponding and the projection 7 and adjacentto the other end being spaced by a plate 14: having its end shaped tocorrespond to the end of the member 13 to permit of the links falling inone direction only. The links are pivotally secured together by pinssimilar to the pins '10.

In the operation of the invention where it is desired to adjust thewindow the hanging portion 15 of the chain is raised outwardly free ofthe flange 12 by means of the swivel attachment and extended in astraight line over said flange 12 so that the pressure of the hinges 2will draw the chain outwardly through the opening in the flange 11. Whenthe window has opened the required distance the chain is turned slightlyand again folded between the flanges 11 and 12 where it is securelyheld.

It will of course be apparent that when the window is covered by ascreen it is only necessary to slot the frame of said screen toaccommodate the chain 3 and the window may then be adjusted withoutinterfering with said screen.

lVhat I claim is 1. In a window operating device, the combination with awindow adapted to be spring held normally to an open position of avertically channeled bracket secured to the frame of said window,flexible means swivelly secured to said window and pro-v nel, the flangeon the inner side edge terminating slightly short of the upper end ofsaid bracket, and a, chain secured to said wmdow in a swivel o1nt andextend ng through an opening through the outermost of said flanges abovethe inner flange and adapted to be turned downwardly between saidflanges.

3. In a window operating device the combination with a window adapted tobe spring held normally to an open position, of a bracket secured to theframe of said window and provided with flanges at opposite side edgesthereof forming a vertical channel, the flange on the inner side edgeterminating slightly short of the upper end of: said bracket, and a.chain swivelly secured to said window and comprising a alurality ofsolid links pivoted together to fold in one direction only and extendingthrough an opening through the outermost of said flanges above the innerflange and adapted to be turned downwardly between said flanges.

Signed at Toronto, Ont, this 5th day of November, 1918.

CLARENCE VICTOR JONES.
